Levon Helm Band, Jefferson Starship and Country Joe McDonald are among the acts that will descend on Bethel, New York, on August 15th to celebrate the 40th anniversary of the Woodstock Festival, Billboard.biz reports. Mountain, Ten Years After, Canned Heat and Big Brother and the Holding Co. will also play the Bethel Woods Center for the Arts, a venue built on the site of the original Woodstock, which ran from August 15th-17th, 1969.

Helm appeared at the 1969 fest with the Band, while Jefferson Starship took the Woodstock stage as Jefferson Airplane. With the exception of Big Brother & the Holding Co. — Janis Joplin performed at the '69 concert with the Kozmic Blues Band — the rest of the acts performing on August 15th all had a set at the original Woodstock festival. As Rock Daily previously reported, Richie Havens will also play a Woodstock-related event on August 14th, returning to Bethel to perform "Freedom," the song that opened up the '69 festival, at a media-only event.
